Distribution.
USA
: Florida:
Alachua, Brevard, DeSoto
, Highlands, Indian River, Lake, Martin, Miami-Dade, Nassau, Okeechobee, Orange, Osceola, Pasco, Pinellas, St. Lucie, Volusia counties.
The
species was identified first in
Florida
between
November 2002
and
February
2003
in several
Florida
counties by DPI inspector Kenneth Hibbard. Some specimens of the new species collected during this period are from additional localities but were not restudied for the description.
Thus
, they are not included in the data above.
These
localities (alphabetical by county) include
Palm Bay
(
Brevard County
; FSCA#
E2002-5849
),
Arcadia
(

Most
recently, specimens were collected in
Morningside Nature

Gainesville
(

.
Host plant.
Euthamia graminifolia
(L.) Nutt. (syn.
Euthamia caroliniana
(L.) Greene ex Porter and Britt.) (Compositae). In the Atlas of
Florida
Plants (
Wunderlin et al. 2020
)
Euthamia caroliniana
is considered a valid species; in the World Flora Online (
WFO 2020
), however, it is a synonym of
E.
graminifolia
. All the records from
Florida
are from
E.
caroliniana
.
Derivation of name.
Named after its host genus
Euthamia
.
Comments.
Adults of
Craspedolepta euthamiae
spec. nov.
differ from all other similar North American species, i.e. species with spotted forewings, bearing surface spinules usually forming a hexagonal pattern consisting of a single row of spinules, with a lamellar paramere widening towards the apex, and with distal segment of the aedeagus strongly expanded apically with a small anterior hook, as follows.
Craspedolepta caudata
(Crawford, 1911)
,
C.
minuta
(Caldwell, 1938)
and
C.
numerica
(
Caldwell, 1941
)
have a broader, slightly more curved paramere.
Craspedolepta fumida
(Caldwell, 1938)
,
C. macula
Journet and Vickery, 1979
,
C. maculimagna
Journet and Vickery, 1979
,
C.
nota
Journet and Vickery, 1979
, and
C. scurra
Journet and Vickery, 1979
, have female terminalia that are longer, with the dorsal margin of the proctiger distinctly undulate. The female terminalia of
C. constricta
(
Caldwell, 1936
) also are longer, but the dorsal margin of the proctiger is distinctly concave.
Craspedolepta smithsoniana
Klimaszeski, 1979
, differs in the much smaller apical dilatation of the distal segment of the aedeagus and the much shorter end tube of the ductus ejaculatorius. In
C.
parvula
Journet and Vickery, 1979
, and
C. vulgaris
Journet and Vickery, 1979
, the paramere is similar but the rugose microscultpture on the inner face is much more restricted and the sclerotized end tube of the ductus ejaculatorius is only about half as long as the distal segment of the aedeagus.
Craspdolepta ochracea
(Provancher, 1872)
has similar parameres and aedeagus but lacks dark spots in the forewings, has a shorter end tube of the ductus ejaculatorius, and longer female terminalia.
Virtually nothing is known about the immatures of the North American
Craspedolepta
species. Descriptions exists only for
C. nebulosa
(Zetterstedt, 1840) and
C. subpunctata
(
Foerster, 1848
), two Holarctic species associated with
Epilobium angustifolium
(Onagraceae)
(
Ossiannilsson 1992
). Both species share the 3-segmented antennae with
C.
euthamiae
but differ in the circumanal ring that consists of several rows of pores.
Craspedolepta numerica
was reported “from southwestern
United States
and
Mexico
, though some specimens from Florida seem to fall within this species” (
Journet and Vickery 1979
). From Florida, they mentioned specimens from Garnett, Mascotte and Hilliard which we examined (USNM). The material from Garnett belongs to
C.
numerica
of which we have examined the
types
(USNM) (
Fig. 76–78, 81
), however, Garnett is not in Florida but is in Kansas. The specimens from Mascotte and Hilliard belong to
C.
euthamiae
and constitute a part of the
type
series.
Craspedolepta euthamiae
and
C.
numerica
are similar in body size, forewing shape with spotted membrane (
Fig. 48
), the surface spinules forming hexagonal pattern consisting of a single row of spinules (
Fig. 49
), the shape of the aedeagus (
Fig. 75, 78
) and the female terminalia (
Fig. 79, 81
). They clearly differ in the shape of the paramere and the presence or absence of tubercular microsculpture on the inner surface (
Fig. 73, 74
versus 77).
Craspedolepta nota
was described from
12 adult
specimens from
Canada
(
Alberta
,
Manitoba
) and the
USA
(FL, KS).
Journet and Vickery (1979)
stated that the separation from
C.
caudata
(Crawford, 1911)
,
C. macula
Journet and Vickery, 1979
, and
C.
numerica
is “problematic”. We suspect that
Journet and Vickery’s (1979)
C.
nota
is a species mix, and the specimens from Florida belong to
C.
euthamiae
spec. nov.
